Boor’us Johnson, the UK’s proposed Prime Minister:

boor |bo͝or|
noun
an unrefined, ill-mannered person: at last the big obnoxious boor had been dealt a stunning blow for his uncouth and belligerent manner.
ORIGIN mid 16th cent. (in the sense ‘peasant’): from Low German būr or Dutch boer ‘farmer.’ [from the Oxford]

Just on the outside chance this proposed sobriquet will catch on ; )
